H ORSE-POWER SPEED-REGULATOR.

v SPECIFICATION forming part of Letters Patent'No. 287,327, datedOctober 23, 1883.

Application filed August 31, 1883. (No model.)

To all whom it may concern:

and having brake-pads g on their outerex Be it known that I, JASPER, A.RoUsE, a tremities.

citizen of the United States, residing at East Berkshire, in the countyof Franklin and State of Vermont, have invented certain new and usefulImprovements in Horse-Power Speed- Regulators, of which the following isa specification, reference being had therein to the accompanyingdrawings.

My invention relates to an improvement in devices for preserving uniformmotion in horsepowers and preventing liability to accident, which mightotherwise result from a sudden increase of speed; and it consists of aloose pulley having a split hub, for greater convenience of adjustmentover the wheel-clutch, and a foundation-block provided withweightedarms, and on which two lever-brakes are pivoted, and to which is bolteda leaf-piece, by means of which an adjustable grip is formed, forreadyand reliableatt'achment to the wheelclutch between the loose pulleyand the drivewheel. The whole forms a speed-regulating attachment whichis entirely separate and distinct from the drive-wheel, and soconstructed that it can be attached or removed with the greatestconvenience.

In the accompanying drawings, in which similar letters indicate likeparts, Figure 1 is an elevation showing the relative positions of myspeedregulator and the drive wheel. Fig. 2 is a plan view of my device.Fig. 3 is a side elevation of a horse-power, showing the application ofmy invention. Fig. 4 is a plan view of my foundation-block, with theweighted spring-actuated arms passing through swinging ears andoperating brake-pads. Fig. 5 is a plan view of the loose pulley andsplit hub.

A is the drive-wheel ofahorse-power, which is attached in the usualmanner to the arbor B by means of the clutch O.

D is what I term a foundation-block, designed to be rigidly clamped tothe'clutch 0, inside of the drive-wheel A, and separate from it, asshown in Fig. 1, by means of the leafpiece E, which is bolted to it at d(I, thus forming an adjustable grip around the clutch, so that it may bereadily removed at will. It also forms the support for the weighted armsF and the bell-crank levers G, fulcrumed at e,

H H are swinging ears, through the lipi 011 the end of which the arm Floosely passes. These ears are pivoted to the block D at h, in orderthat they may more readilyiadj ust themselves to the varying positionstaken by the arms F as they move outward and back to place, and thusavoid the tendency to bind the arms to which stationary loops areliable.

J is a regulating-spring coiled around the 7 arm F, between the adjusting-nut j and the lip 45 of the ear H. The arms Fterminate in slottedweights f, which are designed to slide freely on the block D, to whichthey are loosely attached by the flat-head rivets K. By thisconstruction the arms F are made more sensi tive to the action of thecentrifugal force, by which they are carried forward, than they would beif confined to the plane on which they move by fixed loops in theordinary way.

L is a loose pulley, which is so hung on the clutch 0, back of thefoundation-block D, that the brake-pads g g on the outer end of thelevers G may impinge upon its rim and control its motion as they arecarried forward by the outward movement of the arm F, which is 0011-nected with the other extremity of the lever G. It is provided withasplit hub, M, attached to ears upon its rim at n n, for the purpose ofmore conveniently putting it on over the clutch 0, without requiring theclutch-key to be removed, whenever it becomes necessary to shift theregulator.

P is a compound lever fulcrumed at p to the frame of the horsepower, asshown in Fig. 3. Its upper end is connected tothe hub M, at r, of theloose pulley L by the rope s, and its lower end to thelever R, pivotedat v, on which a brake-pad, T, is so arranged that as the lever R israised it is brought in contact with the rim of the drive-wheel A...

In operation the arms F F are set so that the pads g y do not impingeupon the rim of the loose pulley L, and the rope sbeing loose,

the brakepad T is out of contact with the drive- I press tightly againstthe rim of the loose pulley L. This pulley, no longer loose, is thuscompelled to revolve upon the arbor B of the drive-wheel A, therebywinding the rope around its hub M, which draws down the end of the leverP, and at the same time raises the lever B until the brake-pad T ispressed against the rim of the drivewheel. The speed of the drive-wheelis thereby checked until by the re duction of the centrifugal force theweighted arms F F are drawn back by the action of the spiral spring J,and the pads g graised. The pulley L, being thus free from the pressureof the pads g g, againbecomes loose and relieves the rope s from itsstrain around the hub M, and also the driving-wheel from the pressure ofthe pad T.

, The degree of centrifugal force required to move the weighted arms F Fis regulated at will by varying the tension of the spring J by theadjustment of the nut 5.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

- 1. In a speed-regulator, the combination of levers P and R, combinedtogether and with the drive-wheel A, substantially as shown, and for thepurpose set forth.

3. In speed-regulators, the foundation-block D and 1eaf-piece E, bywhich it may be readily attached to the clutch C, substantially asdescribed.

4. The combination, in speed-regulators, of 40 the weighted armsF,-adjustable spring J,

swinging ear H, and brake-levers G, with the foundation-block D andleaf-piece E, substantially as set forth.

In testimony whereof I do aflix my signa- 45 ture in presence of twowitnesses.
